[0023] S5: The preset packaging scheme and the preset scheme reliability index of the preset packaging scheme, each of the trial adjustment schemes and the trial scheme reliability index of each of the trial adjustment schemes are taken together as a packaging scheme evaluation set for the packaging target; the packaging scheme evaluation set is used to provide several trial adjustment schemes for the packaging target, and to evaluate the packaging reliability of the preset packaging scheme and the various trial adjustment schemes.

[0024] Specifically, in step S1 of the embodiment provided by the present invention, a preset packaging scheme corresponding to the packaging target is first obtained, wherein the packaging target is a semiconductor device to be packaged, such as a chip, and the preset packaging scheme is a packaging scheme prepared for the packaging target, that is, a description of the overall state of the packaging target after the packaging operation is completed.

[0025] More specifically, the preset packaging solution usually includes a set of packaging structures for the packaging target, materials selected for each specific part of the packaging structure, and the relationship between each specific part.

[0026] More specifically, collect and organize basic data related to the packaging target, such as geometric dimensions, material properties, thermodynamic parameters, etc., select appropriate modeling tools or simulation software, such as ANSYS, COMSOL, SolidWorks, etc., model according to needs, and based on the preset packaging solution, input the collected basic data into the modeling tool to build a 3D model of the packaging target.

[0027] It can be understood that the packaging simulation model is to digitally simulate the packaging target that implements the preset packaging scheme, and calculate the response of the packaging target under the preset packaging scheme, including temperature distribution, stress distribution, deformation, etc. The simulation results can be visualized through a graphical interface.

[0028] Specifically, in step S2 of the embodiment provided by the present invention, deduction and simulation processing of the forward time dimension and the backward time dimension are performed based on the packaging simulation model to obtain a packaging process deduction and simulation model and a packaging effect deduction and simulation model corresponding to the packaging simulation model.

[0029] More specifically, the forward time dimension deduction simulation processing of the packaging simulation model is the simulation deduction processing of the packaging process of the packaging simulation model. The obtained packaging process deduction simulation model is a simulation of each step of the packaging simulation model obtained by performing packaging operations on the packaging target. The purpose of this simulation is to evaluate the execution reliability of the packaging process.

[0030] More specifically, the backward time dimension simulation processing of the packaging simulation model is a simulation processing of the finished packaging product that has completed the packaging operation under various expected stress scenarios in the future, that is, predicting the working reliability of the finished packaging product in future use.

[0031] Specifically, in step S3 of the embodiment provided by the present invention, packaging evaluation processing is performed respectively according to the packaging process deduction simulation model and the packaging effect deduction simulation model to obtain the process reliability index and effect reliability index of each packaging element of the preset packaging solution.

[0032] More specifically, according to the packaging process deduction simulation model, a packaging evaluation is performed to obtain a process reliability index of each packaging element of the preset packaging scheme, and according to the packaging effect deduction simulation model, a packaging evaluation is performed separately to obtain an effect reliability index of each packaging element of the preset packaging scheme; wherein, the process reliability index is the reliability degree of the execution process of packaging by executing the scheme, and the effect reliability index is the reliability degree of maintaining stability under various stress scenarios after the packaging is completed.

[0033] More specifically, a packaging element is a component of a solution that participates in the packaging design of a packaging target. Each basic component corresponds to a packaging element, and the combination of the basic components completes the packaging process of the packaging target.

[0034] More specifically, the process reliability index and effect reliability index of each packaging element are integrated. The weighted average method, comprehensive scoring method and other methods can be used for integration, and the comprehensive reliability index of all packaging elements can be summarized to calculate the overall reliability index of the preset packaging solution. This index can reflect the comprehensive reliability of the entire packaging solution in different dimensions.

[0035] It can be understood that through the calculation and integration of the process reliability index and the effect reliability index, a comprehensive reliability evaluation of the packaging solution can be achieved, providing detailed data support to help engineers identify and solve potential problems in the packaging process, optimize packaging design and process, and improve the packaging solution based on the evaluation results of the reliability index, thereby improving the overall quality and reliability of the product. Through reliability evaluation, potential risks in the packaging solution can be identified in advance, and prevention and control measures can be formulated to reduce the risk of failure.

[0036] Specifically, in step S4 of the embodiment provided by the present invention, the packaging reliability index of each packaging element in the preset packaging scheme is extracted as the basic data for subsequent adjustment and evaluation, and according to the overall reliability index of the preset packaging scheme, the key weak links and packaging elements to be optimized are identified, and the specific adjustment goals and directions are determined.

[0037] More specifically, based on the adjustment targets, different adjustments and optimizations are made to the various packaging elements of the preset packaging scheme to generate several trial adjustment schemes. The adjustment contents may include material selection, process parameter optimization, structural design improvement, etc. Each trial adjustment scheme is described in detail, and the specific adjustment contents and expected effects of each packaging element are recorded.

[0038] More specifically, a packaging process deduction simulation model and a packaging effect deduction simulation model are used to simulate and evaluate each trial adjustment plan, and its process reliability index and effect reliability index are calculated. The process reliability index and effect reliability index of each trial adjustment plan are recorded and analyzed to obtain its trial plan reliability index. The reliability index of each packaging element of each trial adjustment plan is integrated to calculate the overall trial plan reliability index. The trial plan reliability indexes of each trial adjustment plan are compared, the advantages and disadvantages of each plan are analyzed, and the optimal adjustment plan is identified.

[0039] It can be understood that the detailed analysis and evaluation based on the packaging reliability index can guide the optimization adjustment of the packaging solution, ensure the scientificity and effectiveness of the adjustment solution, and gradually improve the overall reliability of the packaging solution through the generation and evaluation of the trial adjustment solution to ensure the high performance and high reliability of the final solution. The trial adjustment solution can be simulated and evaluated in a virtual environment to reduce the cost and time of actual testing and adjustment, improve R&D efficiency, and provide intuitive and comparable evaluation results through quantitative reliability index to help engineers make scientific and objective decisions.

[0040] Specifically, in step S5 of the embodiment provided by the present invention, based on the preset scheme reliability index, several adjustment strategies are proposed, and multiple trial adjustment schemes are generated. Each adjustment element of each trial adjustment scheme is recorded in detail, including information such as adjustment content and expected effect. The simulation tools or experimental means of the preset packaging scheme in the above steps are used to simulate and evaluate each trial adjustment scheme, and the reliability index of the trial scheme is calculated.

[0041] More specifically, the reliability evaluation results of each trial adjustment scheme are recorded, and its reliability index is analyzed. The preset packaging scheme and its preset scheme reliability index, and each trial adjustment scheme and its trial scheme reliability index are jointly constructed into a packaging scheme evaluation set. All schemes and reliability indices are integrated to form a complete evaluation data set, which is convenient for unified comparison and analysis.

[0042] More specifically, based on the packaging scheme evaluation set, several trial adjustment schemes are provided for the packaging target for decision-making reference, and a comprehensive evaluation is conducted on the preset packaging scheme and each trial adjustment scheme, and the packaging reliability index of each scheme is compared. According to the reliability index in the packaging scheme evaluation set, the schemes are compared and the optimal packaging scheme is selected.

[0043] It can be understood that constructing a packaging scheme evaluation set, systematically collecting and managing the information and reliability index of the preset schemes and each trial adjustment scheme, facilitates unified evaluation and comparison, provides several trial adjustment schemes, increases optimization space and room for choice, and can better meet diverse packaging target requirements.

[0048] S12: constructing corresponding element simulation units respectively according to the respective package elements, and performing unit setting simulation processing on the respective element simulation units according to the element layout parameters of the respective package elements, so as to obtain the package simulation model.

[0049] Specifically, the target object to be encapsulated and its specific requirements are clarified, and a preset encapsulation solution corresponding to the encapsulation target is obtained. The preset encapsulation solution is a encapsulation solution prepared to be applied to the encapsulation target.

[0050] More specifically, the preset packaging scheme is analyzed in detail to decompose several packaging elements (for example, chips, substrates, interconnect structures, packaging materials, etc.), the specific layout of each packaging element is analyzed, and its element layout parameters (for example, position, size, shape, relative position, etc.) are identified and recorded.

[0051] More specifically, corresponding element simulation units are constructed according to each packaging element to ensure that each unit can accurately represent its actual packaging function and characteristics. Parameters are set for each element simulation unit according to the identified element layout parameters to ensure that the configuration of the simulation unit is consistent with the actual layout.

[0052] More specifically, all element simulation units are integrated together to form an overall packaging simulation model, the integrated packaging simulation model is simulated to verify the interaction between each element and the overall performance, necessary optimization adjustments are made, preliminary simulations and tests are performed to ensure the accuracy and reliability of the packaging simulation model, and through more in-depth simulations and experiments, the performance of the packaging simulation model under various working conditions is verified to ensure that it meets the requirements of the packaging objectives.

[0053] It can be understood that by decomposing and analyzing the packaging elements of the preset packaging solution and constructing simulation units based on detailed element layout parameters, the accuracy and representativeness of the packaging simulation model are ensured. The constructed packaging simulation model can perform efficient simulation and optimization, quickly evaluate the feasibility and performance of various design solutions, and reduce the time and cost of actual experiments. The packaging simulation model can perform comprehensive reliability assessments, predict possible failure modes and reliability issues, and prevent and improve them in advance.

[0054] Preferably, the step of performing deduction simulation processing in the forward time dimension based on the packaging simulation model to obtain a packaging process deduction simulation model corresponding to the packaging simulation model includes:

[0055] S21: Analyze and process the packaging step sequence of each element simulation unit of the packaging simulation model according to the preset packaging scheme to obtain the preset packaging steps of each element simulation unit corresponding to the packaging simulation model; wherein the preset packaging steps are used to describe the use sequence of the element simulation units in the process of constructing the packaging simulation model according to the preset packaging scheme;

[0057] S23: integrating the packaging step simulation units of the element simulation units to obtain a packaging process deduction simulation model of the packaging simulation model.

[0058] Specifically, according to the preset packaging scheme, identify and record the specific steps and sequence of each element simulation unit in the packaging process, conduct detailed analysis on the preset packaging steps of each element simulation unit, and clarify its specific operations and arrangement sequence in the packaging process.

[0059] More specifically, based on the element layout parameters obtained in the early stage, the specific position and status of each element simulation unit in the encapsulation step are further refined and extracted; based on the element layout parameters and the preset encapsulation steps, a corresponding encapsulation step simulation unit is created for each element simulation unit; the execution process of the encapsulation step simulation unit is simulated to ensure that each unit can accurately reflect its actual encapsulation operation in a digital environment.

[0060] More specifically, all packaging step simulation units are integrated to form an overall packaging process deduction and simulation model, and the integrated packaging process deduction and simulation model is verified to ensure that the sequence and execution process of each packaging step are accurate, and adjustments and optimizations are made as needed.

[0061] It is understandable that through the deduction and simulation of the forward time dimension, each step and operation in the packaging process can be accurately reproduced, providing detailed packaging process data. The packaging process deduction and simulation model can help engineers discover the weak links in the packaging process, perform targeted optimization, and improve the efficiency and reliability of the packaging process.

[0062] Preferably, the step of performing a backward time dimension deduction simulation process based on the packaging simulation model to obtain a packaging effect deduction simulation model corresponding to the packaging simulation model includes:

[0063] S24: performing packaging environment analysis and processing on each of the element simulation units of the packaging simulation model in turn to obtain a packaging test environment model of each of the element simulation units in the packaging simulation model; wherein the packaging test environment model is used to feedback the environmental impact effect of the packaging environment in which the element simulation unit is located on the element simulation unit;

[0067] S28: Combining the element arrangement axis with the test deduction axis to obtain a packaging effect deduction simulation model corresponding to the packaging simulation model.

[0068] Specifically, environmental data related to the packaging process are collected, including parameters such as temperature, humidity, and pressure. The environment in which each element simulation unit is located during the packaging process is analyzed to determine the impact of environmental factors on the element simulation unit. Based on the analysis results, a packaging test environment model is created for each element simulation unit to simulate the impact of environmental factors on it.

[0069] More specifically, the arrangement order and position of each element simulation unit are determined to form an element arrangement axis, and the packaging test environment model corresponding to each element simulation unit is sequentially arranged on the element arrangement axis to form an overall element arrangement structure.

[0070] More specifically, the different stress environment factors that the packaging process may experience (such as mechanical stress, thermal stress, electrical stress, etc.) are determined, and a corresponding stress test environment model is created for each stress environment to simulate the performance of the packaging model under different stress conditions.

[0071] More specifically, the arrangement order and position of the stress test environment model are determined to form a test deduction axis, and several stress test environment models are sequentially arranged on the test deduction axis. The element arrangement axis is combined with the test deduction axis so that each element simulation unit is simulated in the corresponding stress environment. The combined model is the packaging effect deduction simulation model, which can simulate the performance of each element in the packaging process under different environments.

[0072] It can be understood that through the packaging test environment model, the impact of the packaging environment on each element simulation unit can be comprehensively evaluated to provide a reliable basis for packaging design. The packaging effect deduction simulation model can predict the performance during the packaging process and help designers identify potential problems in advance. Based on the simulation results, the packaging solution can be optimized to improve the reliability and effectiveness of the packaging process.

[0073] Preferably, the step of performing packaging evaluation processing according to the packaging process deduction simulation model to obtain the process reliability index of each packaging element of the preset packaging solution includes:

[0074] S31: generating a corresponding evaluation execution ordinal number for each packaging step simulation unit according to the preset packaging step corresponding to each packaging step simulation unit in the packaging process deduction simulation model; wherein the evaluation execution ordinal number is used to describe the processing order of packaging evaluation processing for the packaging step simulation unit;

[0077] Specifically, according to each packaging step in a preset packaging scheme, the packaging step simulation unit in the packaging process deduction simulation model is matched, and a corresponding evaluation execution ordinal number is generated for each packaging step simulation unit. The ordinal number is used to describe the order of packaging evaluation processing on the packaging step simulation unit.

[0078] More specifically, according to the generated evaluation execution ordinal number, the packaging step simulation units are arranged in sequence to form an evaluation execution sequence, and the evaluation execution sequence is checked to ensure that the arrangement order of each packaging step simulation unit complies with the logic and process flow of the preset packaging steps.

[0079] More specifically, prepare tools and methods for evaluating package reliability, ensure consistency in standards and parameters used in the evaluation process, perform package reliability evaluation on each package step simulation unit in the evaluation execution sequence in turn, and record the process reliability index of each step.

[0080] More specifically, the process reliability index of each packaging step simulation unit is recorded, the recorded process reliability index is assigned to the packaging element of the corresponding packaging step simulation unit, the process reliability index of each packaging element is summarized, a comprehensive report is generated, the reliability data in the comprehensive report is analyzed, and the overall reliability level of the packaging solution is determined.

[0081] It is understandable that the preset packaging steps and the packaging process deduction simulation model are combined to ensure the evaluation accuracy of each packaging step simulation unit, reduce human errors, and conduct independent reliability evaluation on each packaging step to ensure that the process reliability index of each packaging element can fully reflect the actual situation of the packaging process. By evaluating the execution sequence and recording the process reliability index, the traceability of the packaging evaluation is provided to facilitate subsequent verification and optimization. Based on the reliability evaluation results, designers can identify and improve the weak links in the packaging process, optimize the packaging design, and improve product quality.

[0091] S312: Perform weighted evaluation processing on the preceding success index, the preceding stability index, and the succeeding stability index of the packaging step simulation unit to be evaluated, so as to obtain a process reliability index of the packaging step simulation unit.

[0092] Specifically, the packaging step simulation unit to be evaluated is analyzed to obtain its specific step execution characteristics, which are used to describe the execution mode of the unit, such as operating parameters, environmental requirements, etc.

[0093] More specifically, according to the evaluation execution sequence, several packaging step simulation units before the packaging step simulation unit to be evaluated are determined, and these units are used as preceding steps. According to the element layout parameters of each element simulation unit in the preceding step, these element simulation units are laid out to form a preceding layout environment.

[0094] More specifically, based on the preceding layout environment, the execution success probability of the step execution characteristics of the packaging step simulation unit to be evaluated is analyzed to obtain a preceding success index, and according to the step execution characteristics of the packaging step simulation unit to be evaluated, the environmental damage probability analysis of the preceding layout environment is performed to obtain a preceding stability index.

[0095] More specifically, according to the evaluation execution sequence, several packaging step simulation units after the packaging step simulation unit to be evaluated are determined, and these units are used as subsequent steps. According to the element layout parameters of the element simulation units in the preceding steps and the steps to be evaluated, these element simulation units are laid out to form a layout environment to be evaluated. Based on each packaging step simulation unit in the subsequent steps, the probability of environmental damage is analyzed for the layout environment to be evaluated in turn to obtain a subsequent stability index.

[0096] More specifically, a weighted evaluation is performed on the preceding success index, the preceding stability index and the following stability index of the packaging step simulation unit to be evaluated to obtain a process reliability index.

[0097] It can be understood that by analyzing the execution characteristics and layout environment of each step in detail, the reliability of the packaging step simulation unit can be accurately evaluated, including various influencing factors of the preceding and subsequent steps, and the various variables in the entire execution sequence are fully considered, which improves the accuracy and comprehensiveness of the evaluation. The evaluation process takes into account the dynamic interactions and environmental impacts between different steps, and can make reasonable predictions about changes in the actual execution process.

[0098] Preferably, the step of performing packaging evaluation processing according to the packaging effect deduction simulation model to obtain the effect reliability index of each packaging element of the preset packaging solution includes:

[0099] S313: performing simulation test evaluation processing on each of the packaging test environment models on the element arrangement axis in turn according to the various stress test environment models on the test deduction axis to obtain test simulation results of each of the packaging test environment models under each of the stress test environment models, and evaluating and scoring the test simulation results according to preset standards to obtain the corresponding effect reliability score;

[0100] S314: performing weighted evaluation processing on the effect reliability scores of the packaging test environment model corresponding to each of the pressure test environment models to obtain the effect reliability index of the packaging test environment model, and assigning the effect reliability index of the packaging test environment model to the element simulation unit of the corresponding packaging test environment model to obtain the effect reliability index of the element simulation unit;

[0101] The step of performing simulation test evaluation processing on the packaging test environment model according to the stress test environment model to obtain a test simulation result includes:

[0102] S3131: Generate corresponding environmental pressure characteristics according to the pressure test environment model, and perform correction processing on the packaging test environment model according to the environmental pressure characteristics to obtain a packaging test correction model of the packaging test environment model corresponding to the environmental pressure characteristics; wherein the packaging test correction model is used to feed back the environmental impact effect of the packaging test environment model on the element simulation unit after receiving the pressure impact of the pressure test environment model;

[0103] S3132: Analyze the stability of the element simulation unit according to the package test correction model to obtain the effect reliability index of the element simulation unit.

[0104] Specifically, various stress test environment models are set on the test simulation axis, which simulate different environmental stress conditions, such as temperature, humidity, vibration, shock, etc., and various packaging test environment models are set on the element arrangement axis, which represent different packaging conditions and configurations.

[0105] More specifically, a corresponding environmental pressure feature is generated according to each stress test environment model. These features describe specific stress conditions and parameters. The packaging test environment model is corrected for the impact of environmental pressure according to the environmental pressure feature to generate a packaging test correction model. The packaging test correction model reflects the performance of the packaging test environment model under specific stress conditions.

[0106] More specifically, each packaging test environment model is simulated under each stress test environment model to obtain test simulation results. These results show the performance of the packaging test environment model under different stress conditions, and each test simulation result is evaluated and scored according to preset standards to obtain an effect reliability score. These scores reflect the reliability of the packaging test environment model under specific stress conditions.

[0107] More specifically, a weighted evaluation is performed on the effect reliability score of each packaging test environment model under different stress test environment models to obtain the effect reliability index of the packaging test environment model, and the effect reliability index of the packaging test environment model is assigned to the corresponding element simulation unit to obtain the effect reliability index of each element simulation unit. Based on the packaging test correction model, a stability analysis is performed on the element simulation unit to further confirm its effect reliability index.

[0108] It is understandable that by setting a variety of stress test environment models, the performance of the packaging test environment model under different conditions can be comprehensively evaluated to ensure the comprehensiveness and accuracy of the evaluation results. By generating environmental pressure characteristics and performing correction processing, the performance of the packaging test environment model under actual stress conditions can be truly reflected to improve the realism and reliability of the evaluation. Through meticulous simulation tests and preset standard evaluation scoring, the obtained effect reliability score accurately reflects the reliability of the packaging test environment model. Through weighted evaluation, the performance under different stress conditions can be comprehensively considered to comprehensively evaluate the overall reliability of the packaging test environment model. Through stability analysis, the reliability of the element simulation unit under different stress conditions can be further confirmed to ensure the stability and reliability of the evaluation results. The evaluation results can be used to optimize the packaging solution, select the most reliable packaging element configuration, and improve the overall quality and reliability of the packaging process.

[0109] Preferably, the step of integrating the process reliability index and the effect reliability index of each packaging element to obtain the preset solution reliability index of the preset packaging solution comprises:

[0110] Performing weighted integration processing on the process reliability index and the effect reliability index of the packaging element to obtain the element reliability index of the packaging element;

[0111] The element reliability index of each packaging element is averaged to obtain the preset solution reliability index of the preset packaging solution.

[0112] Specifically, the process reliability index of each packaging element is collected and sorted. These indexes reflect the reliability of the packaging element in the actual production process, and the effect reliability index of each packaging element is collected and sorted. These indexes are obtained through simulation testing and evaluation, and reflect the performance of the packaging element under different stress conditions.

[0113] More specifically, based on the importance of the packaging element in the overall packaging solution and the impact of its process reliability and effect reliability on the final product, the weighting coefficients of the process reliability index and the effect reliability index are determined, and the process reliability index and effect reliability index of each packaging element are weighted and integrated.

[0114] More specifically, the element reliability index is obtained, and according to the above-mentioned weighted integration formula, the element reliability index of each packaged element is calculated and obtained, and the element reliability indexes of all packaged elements are averaged.

[0115] It can be understood that by integrating the process reliability index and the effect reliability index, the comprehensive reliability of each packaging element can be comprehensively evaluated, taking into account both the performance in the actual production process and the performance under different pressure conditions. By determining the weighting coefficient, the weights of process reliability and effect reliability in the overall reliability evaluation can be flexibly adjusted to adapt to different packaging solutions and actual needs. The weighted integration processing improves the accuracy of the reliability evaluation and makes the evaluation results more scientific and accurate. The preset scheme reliability index is obtained through mean calculation processing, which can provide a scientific basis for the optimization and decision-making of the packaging solution, select the optimal packaging solution, and improve the overall quality and reliability of the product. The integration processing and mean calculation processing can conduct a systematic analysis of the reliability of the packaging elements, which helps to identify and solve the weak links in the packaging process and improve the stability and reliability of the overall packaging process.

[0116] Preferably, based on the packaging reliability index of each packaging element of the preset packaging solution, the preset packaging solution is subjected to trial adjustment processing to obtain several trial adjustment solutions of the preset packaging solution, the step includes:

[0117] S41: performing an index comparison process on the packaging reliability index of each packaging element of the preset packaging solution, and generating a reliability ordinal number of each packaging element according to the result of the index comparison process;

[0118] S42: performing parameter adjustment processing on the element layout parameters of the package element having the lowest reliability ordinal number to obtain a plurality of adjusted layout parameters;

[0119] S43: Substituting a plurality of the adjustment layout parameters into the preset packaging schemes for replacement processing, so as to obtain a plurality of trial adjustment schemes.

[0120] Specifically, the packaging reliability index of each packaging element in the preset packaging scheme is collected, and these packaging reliability indexes are compared and ranked to generate a reliability ordinal for each packaging element. The reliability ordinal reflects the relative reliability of the packaging element. The lower the ordinal, the worse the reliability. Find the packaging element with the lowest reliability ordinal, that is, identify the weakest link in the current packaging scheme.

[0121] More specifically, for the identified packaging elements, the element layout parameters are adjusted. The layout parameters include but are not limited to position, size, material, etc., and several different adjusted layout parameters are determined for subsequent replacement and testing. Each adjusted layout parameter is substituted into the preset packaging solution, replacing the original layout parameters, and generating several trial adjustment solutions. Each replaced packaging solution is a trial adjustment solution. These solutions will be used for subsequent experiments and evaluations to determine their reliability and optimization effects.

[0122] It is understandable that through reliability ordinal comparison, the weakest packaging element in the packaging solution can be accurately identified, and resources and energy can be concentrated on optimization. By adjusting the layout parameters in a variety of ways, several trial adjustment schemes can be generated to form a diversified optimization path and increase the possibility of success. By adjusting the layout parameters of the weakest link in a targeted manner, the overall reliability of the packaging solution can be significantly improved, and the product quality can be improved. The use of systematic adjustment and evaluation methods can ensure that each trial adjustment scheme is scientifically verified, which helps to find the optimal packaging solution.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
